In many areas of luxury the end consumer is often met with the finished product with little idea of how that product was actually developed the way it was, nor why. Here A. Lange & Sohne provides a fascinating insight into how it approached three technical areas of watch*** and reveal how each of those paths evolved.The first of Lange's innovations for 2010 is harder gold (top). Chemically speaking, this novel "honey-coloured" gold is an 18-carat gold alloy which means it consists of 75 percent pure gold. Its colour lies midway between pink and white gold and is attribut-able to its copper and zinc content.The combination of a special thermal treatment with a slight admixture of man-ganese is responsible for its extraordi-nary hardness which registers between 300-320 HV on the Vickers scale. To put that in perspective, yellow gold's value lies between 135-150 HV meaning honey-coloured gold is more than twice as hard. The benefits to the watchmaker and the wearer are obvious, offering far improved scratch resistance and durability.Meanwhile another of Lange's discoveries for 2010 centres round its Zeitwerk timepiece (above) which boasts numerals that are obscured behind the dial for most of the day. To ensure the wearer can read the time in the dead of night, the numerals’ ability to absorb light had to be addressed.Lange's solution was to create a sapphire-crystal dial with a semi-transparent but UV-permeable coating. The light in the ultra-violet (UV) range from 250 to 430 nanometres is allowed to pass unhindered so the Superluminova numerals can be charged up with photonic energy even when obscured behind the dial. This allows them to glow for several hours at night despite not seeing sunlight in the traditional sense for much of the day.The final innovation likewise involves luminosity but is related to lunar discs rather than numerals. Lange's 1815 Moonphase is accurate to such a degree that it takes over a thousand years for the display to be off by one day relative to the moon's position. Maintaining this excellence, Lange wanted to develop a coating for the stars that would genuinely emulate the appearance of the night sky.The brand employed a group of scientists who pioneered a new process in the watch*** industry in which they apply extremely hard carbon films to the solid-gold lunar discs through physical vapour deposition �C known as PVD. This adjustment of the su***ce not only delivers the desired col-our hue but also very high wear resistance. The lunar discs are crisp and brilliant.

The unveiling of a monument to Ferdinand A. Lange by 15 apprentices of the company's own watchmaker school was the highlight of a ceremony at which Lange Uhren GmbH inaugurated the A. Lange & Sohne Park in Glash��tte on 15 July. With this, the company pays tribute to the founder of Germany's fine watchmaking industry, who opened the first watchmaker workshop in the region in 1845 with 15 apprentices. Also among the more than one hundred guests was his great grandson Walter Lange, who has carried on the family tradition since reunification, as well as the Vice President of the Saxon State Parliament, Andrea Dombois. In her word of welcome she honoured the social involvement of the company which is expressed in so many ways, even beyond the creation of highly qualified jobs. A current example is the tourist guide system for Glash��tte, recently initiated by Lange, which guides visitors to the sights of the city. The more than 3,000 square metre park was designed by the landscape architects Michael Wolf and Dirk Radzanowski from Penig in Saxony, and built by the company Gr��nkonzept from Bannewitz near Dresden. The bronze bust of Ferdinand A. Lange is the work of the Swiss sculptor, Beat K��nzler. A musical setting at the ceremony was provided by the American mezzo-soprano Emily Righter and the Italian baritone Andr�� Schuen. Both are stipendiaries of the "Young Singers Project" of the Salzburg Festival, with which the company maintains a close partnership. This coming Sunday, visitors who come to the city of Glash��tte can be the first to discover a new park abound with roses, hedges, ornamentals, and grasses. On the occasion of the summer festival organised by the S?chsische Zeitung, A. Lange & Sohne is opening the doors to its manufactory and inviting the public to get acquainted with precision watchmaking in many different ways. The planned ascents in a tethered balloon are likely to be very popular: they offer a totally new outlook on Glash��tte as a hub of horology.
